public bool zero_device (string device) throws Error
write zeroes to an entire device
This command writes zeroes over the entire device. Compare with zero
which just zeroes the first few blocks of a device.
If blocks are already zero, then this command avoids writing zeroes. This prevents the underlying device from becoming non-sparse or growing unnecessarily.
